Info on this particular Kachina:

Hopi Morning Singers, (Talavai Kachinas) used to appear in pairs on the rooftops and sing songs, waking the Hopi people in the village. During the day, they would dance with the other kachinas, whom they led and prompted in the singing. They still appear with the other kachinas in the Powamu Ceremony [Bean Planting Festival] and are most often standing in a set to one side of the main movement of the procession. Occasionally, they sing as they stand holding their spruce trees and ringing their bells. –[source: MorningSinger.com]

That's a very cool find! I'd love to have someone assembling a "grab bag" for me, each time I go into a store! That is awesome! 😃
